The Temperature Isn't The Only Thing Rising...
I was happy to read that the BMW ActiveE, the successor to the MINI-E will have a thermal management system that will warm or cool the battery pack to keep it at optimum operating efficiency. This is a feature that is dearly missed on the MINI-E and some of the other pioneers have been very critical of the car because of this omission. The reduced range in the winter months has caused some of the MINI-E drivers to lose faith in the car and not drive as much as they would like to. There are others, myself included who just adjusted their driving to accommodate the 20 or 30 less miles per charge that the car was getting. Then there were others like Jim McLaughlin (MINI-E # 458) who use a automobile cabin heater to pre-heat the cabin and thus the batteries. Jim has continued to record single-charge range well over 100 miles for the entire winter, even when the temperature was down under 20 degrees. To me this is good news because it proves that a sophisticated thermal management system will allow the car to travel roughly the same distance regardless of the outside temperature.
